Removal

NOTICE: The turbocharger compressor vanes can be damaged by even the smallest particles. When removing any turbocharger or engine air intake system component, ensure that no debris enters the system. Failure to do so may result in damage to the turbocharger.

NOTE: Removal steps in this procedure may contain installation details.

Right Hand Camshaft Position (CMP) Sensor

1. NOTICE: Do not pull the engine appearance cover forward or sideways to remove. Failure to press straight upward on the underside of the cover at the attachment points may result in damage to the cover or engine components.

   1. Remove the engine appearance cover nut.
      
   2. Place your hand under the engine appearance cover at each grommet location and pull straight up to release each grommet from the studs.
      
   3. After all of the grommets have been released from the studs, remove the appearance cover from the engine.
      

1. NOTE: The crankcase vent tube may have either a permanent or quick connect connector at one or both ends. If the tube needs to be removed for any reason, the permanent connector(s) must be cut to remove the tube. The tube will then need to be replaced.

   NOTE: If the crankcase vent tube is replaced, the replacement part may not come with a crankcase pressure sensor. If so, the PCM will need to be reprogrammed.

   • If equipped, disconnect the wiring harness electrical connector.
     
   • If necessary, cut the lock tab.
     Use the General Equipment: Side Cutter Pliers
   • If either crankcase vent tube connector was cut, remove and discard the crankcase vent tube.
